Anthropogenic change exposure scores for individual Common Cuckoo, <em>Cuculus canorus</em>

<strong>risk_scores_per_bird-season.csv </strong> Mean and accumulated composite anthropogenic change exposure scores for 239 <em>Cuculus canorus</em> bird-seasons. Change exposure was calculated by combining ten years of tracking data from the British Trust for Ornithology Cuckoo Tracking Project with threat maps capturing direct mortality threats, habitat change, and climate change. Dataset includes metrics of autumn migratory route longitude at a bird-year level; an additional column indicates whether the bird-season is considered data-poor. <br> <strong>aggregated_risk_scores_per-site.csv</strong> Anthropogenic change exposure scores aggregated across bird-seasons from each of the eleven breeding site locations, and associated breeding site population change (calculated using BTO Bird Atlas Frequency Indices). <br> <strong>aggregated_risk_scores_per-site_data_poor_removed.csv</strong> As above, but where aggregated anthropogenic change exposure scores have been calculated excluding data-poor bird-seasons.**risk_scores_per_bird-season.csv**：本数据集收录了239个**大杜鹃（Cuculus canorus）**鸟类季的人为变化暴露综合评分的均值与累计值。该人为变化暴露评分通过整合英国鸟类学信托基金会（British Trust for Ornithology, BTO）杜鹃追踪项目十年的追踪数据，与涵盖直接致死威胁、栖息地变化及气候变化的威胁地图计算得到。数据集包含以鸟类年为统计单位的秋季迁徙路线经度指标；额外设有一列用于标注该鸟类季是否被归类为数据匮乏样本。 **aggregated_risk_scores_per-site.csv**：本数据集包含11个繁殖位点的全部鸟类季的人为变化暴露评分聚合结果，以及对应繁殖位点的种群变化情况（该种群变化通过BTO鸟类图谱频率指数计算得出）。 **aggregated_risk_scores_per-site_data_poor_removed.csv**：本数据集与上述aggregated_risk_scores_per-site.csv数据集内容一致，但聚合后的人为变化暴露评分在计算时已剔除所有数据匮乏的鸟类季样本。
